Police have uncovered a cache containing 500 kilograms of TNT hidden in 10 sacks near the border with the Gaza strip, an Egyptian security official said Tuesday. The official said that the TNT was found in a deserted area 500 meters away from the Rafah border crossing between Egypt and Gaza. He spoke on condition of anonymity Tuesday because he was not authorized to talk to the media. Both the US and Israel have pressured Egypt to do more to stop the illegal flow of weapons across the border into Gaza. The official says police found a second weapons cache Tuesday in Qudaima village in central Sinai. It contained a few packets of TNT and weapons left over from Egypt's wars with Israel, including mortar shells and rockets.
